That MSNBC's hosts tend to discuss actual current events. Fox's hosts often dwell on things like "blockbuster video seen for the first time" (the first time since it was intially covered 5 years ago) that supposedly has Obama going off on a racist rant. They like stories on Obama links to "socialists" and "extemists." If you're an author with a nutjob conspiracy theory, Fox will dedicate an evening to you.
